ETFs (Exchange-Traded Funds)
A fund that holds a basket of securities and trades on an exchange like a stock throughout the day.
What is it?
An ETF is a pooled investment fund holding a basket of underlying securities (stocks, bonds, or both), with shares that trade on an exchange throughout the trading day.
How does it work?
Most ETFs passively track an index, though actively managed ETFs also exist. Shares can be bought or sold at any point during market hours at the current market price.
Why do people use it?
Used to gain diversified exposure to a market, sector, or strategy in a single purchase, often at a low cost.

Potential disadvantages

- Trading costs/spreads can add up with frequent trading
- Niche or leveraged ETFs can carry additional complexity and risk
Risks
- Market risk of the underlying holdings
